In its native habitat, rattlesnake plant produces small yellow flowers in late spring. But as a houseplant, it is grown exclusively for its long, elegant, ornamental foliage, as it rarely blooms indoors. Plants typically grow to about 20 inches tall when grown as houseplants. Rattlesnake plant grows at a moderate rate indoors but will slow or stop growing if the plant is in unfavorable conditions. Because this plant has large leaves, you may be tempted to use commercial leaf shine to give the foliage an extra boost. This can cause browning of the tips of the leaves, so you should stick with a simple damp cloth to remove any dust or debris instead. Although this plant grows in shaded outdoor landscapes in Hawaii and some southern parts of California and Florida, it is most commonly kept as a houseplant or in greenhouses or terrariums. This tropical native needs a lot of heat and humidity to thrive.
Light
Filtered light is the best option. If you want to place your rattlesnake plant in a window, select one that doesn’t have intense afternoon sun streaming through it, or diffuse the light with drapes. A bright spot in a well-lit room works well.
Soil
Choose a well-draining soil. Although these plants can’t handle standing water, they like to be kept moist. A light sandy soil or a potting mix of two parts peat moss and one part perlite works well. Rattlesnake plant prefers slightly acidic or neutral pH levels, but alkaline soils should be avoided.
Water
Over the summer, when your rattlesnake plant experiences the most growth, it needs to be watered frequently to keep the soil or potting mix moist. During the winter season, allow the top layer of soil to dry out before watering again. Rattlesnake plants don’t tolerate waterlogged conditions; if the leaves start to turn yellow, you may be overwatering. Conversely, if the leaves begin to curl unattractively they aren’t receiving enough water. Frequent small waterings are required rather than deep irrigation. Water the plant until it just starts to trickle out of drainage holes (do not water so much that it is streaming out of the bottom). Do not let the plant sit in the excess water. Pour the excess water out and do not pour it back into the plant.
Temperature and Humidity
Ideal temperatures for this plant are around 60 to 75 degrees Fahrenheit. If exposed to prolonged temperatures below this, the leaves can wilt and brown, and will eventually die off. Cold, dry air, poor ventilation, drafts, and sudden temperature changes are all very harmful. Keep your rattlesnake plant away from air conditioning units and heating systems to avoid exposing it to undesired dry air. To create the humid environment the plant favors, stand your potted plant on a tray with pebbles. The water that drains through the pot will remain there and help create the moist conditions that it likes. You can also regularly mist your plant or bring it into the bathroom when showering. Of course, a humidifier is a good investment if you are an avid collector of tropical houseplants.
Fertilizer
Feed your rattlesnake plant every month during the spring and summer growing season. Use a balanced liquid fertilizer to encourage healthy foliage development. For the amount to use, follow the product label instructions.
Types of Rattlesnake Plant
There are cultivars of G. insignis, but there are other species of Goeppertia houseplants with similar care needs:
Goeppertia majestica is a larger 3-foot plant with wider egg-shaped leaves, green with thin stripes of color.Goeppertia makoyana (cathedral windows, peacock plant) is a 40-inch-tall plant with wide showy leaves resembling a peacock’s tail.Goeppertia micans (prayer plant) is a 12- to 16-inch tall plant with leaves that fold together at night.Goeppertia zebrina (zebra plant) is a 3-foot-tall plant with light green leaves striped with darker green.
Pruning
The only pruning required is to remove dead or drying leaves.
Propagating Rattlesnake Plant
These plants are easy to propagate by division once they are well established, but propagation by seed is extremely difficult. You can undertake the process of dividing in the spring when you are planning to repot the plant. Division is a good way to keep plants healthy when they become root-bound and active growth slows down.
Common Pests
The thick leaves of your rattlesnake plant may entice pests. Look underneath leaves for the usual suspects, including aphids, mealybugs, and spider mites. Treat the problem quickly with gentle insecticidal soap, neem oil, or simply wash the insects off the leaves with a soft cloth dipped in soapy water.
Common Problems With Rattlesnake Plants
The leaves and stems of your rattlesnake plant will let you know if there’s a problem. Most of the time it’s due to a watering issue. But here are common issues that you can try to amend for a healthier plant.
Leaf Color or Pattern Fading
A key consideration for any rattlesnake plant is proper lighting. If it gets too much direct sunlight, green spots may appear on the leaves; too little light and the vibrant spotted markings may begin to fade.
Limp or Rotting Stems
There are two possibilities for problematic stems: overwatering or drafts. Giving your plant too much water when the temperature drops can cause the stems to become limp, and sitting in water can cause the roots to rot, which can kill the plant. Try moving the plant to a warmer space with no extreme temperature fluctuations to see how the plant fares.
Leaf Edges Turning Brown
Brown leaf edges signal that the plant needs more humidity in its environment. In addition to brown leaf tips, overly dry air can result in the foliage curling up. Take steps to add humidity to the area where the plant lives.
